To rotate the point \( (9, 5) \) 270 degrees clockwise, we can use the rotation formula. In general, a counterclockwise rotation of 270 degrees is equivalent to a clockwise rotation of 90 degrees.
The formula for rotating a point \( (x, y) \) counterclockwise by 90 degrees is: \[ (x, y) \to (-y, x) \]
Thus, rotating \( (9, 5) \) 90 degrees clockwise gives: \[ (9, 5) \to (-5, 9) \]
Therefore, the new point after a 270-degree clockwise rotation is \( (-5, 9) \).
The correct response is: \[ (-5, 9) \]
